I'm a semi-mac literate user trying to play via winery/wineskin. I followed some reddit directions and installed steam in a wrapper and that worked great. Then I installed Morrowind through steam and that worked great. Then I tried to install OpenMW in a wrapper and there I ran into difficulties. The game loads and the opening audio/video is fine. When it drops me in the game, the audio works and the markers are there, but the rest of the graphics are fubar. Any (very specific- as I'm a winery newbie) directions or suggestions would be greatly appreciated!

Is there a reason you are using Winery instead of the native Mac client? I believe you do need something like Wine in order to acquire the Morrowind files for OpenMW to work, but you want to use the native clients after that on Mac and Linux because they are more performant/reliable.

You don't need Winery to run OpenMW on Mac, only to install the original game off of Steam so you can get the files that you need to use OpenMW. From my understanding the Mac client works fine right now, although you might know something I don't. I will admit I am not a Mac user so hopefully one can come in and help out if the native client isn't working for you.
